DYM4 Middle temperature retarder for oil well cement

DYM4 can stick on the surface of cement hydrate to inhibit contacting between cement and water. also stick on the surface of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry.
Characterstic:
 DYM4 consists of various kind of compounds, such as cellulose derivative and hydroxycarboxylic acid .
 Appearance: pale yellow powder, non-poisonous, non-odor, and non-corrosivity
 Normal dosage:0.1%-1.0%(BWOC) .It is more efficient if it is used combining with USZ friction reducing additive when middle-deep well is cemented it can reduce the consistency of cement slurry and improve the rheology.
 It can deduce consistency of cement slurry and improve the rheology
 Retard the thickening time efficiently
 Generally used in oil wells whose circulate temperature under bore is bellow 110℃
 Preferred to be mixed without water
Technical specification:

The ingredient of the cement in the table is : Jiahua G class cement. W/C0.44 Dosage of DYM4:0.1%-1.0% DYM5:0.4% ,water quality :distilled water

Package,storing and transportation:
 Be sacked with three-layer plastics bag,25KG per bag
 Be kept away from moisture and possible damage of the packages in transportation Be stored in a cool and dry situation .Storage life is two years
